SPE CIPICATION forming part of Letters Patent No. 365,358, dated June 21, 1887.

Application filed March 24, 1887.

1'0 aZZ whom. it may concern.-

Be it known that I, ROBERT VVTJWHITE- HURS'I, a citizen of the United States, residing at Norfolk, in the county of Norfolk and State 5 of Virginia, have invented certain new and useful Improvements in Plows, of which the following is a specification.

My invention relates to certain improve ments in plows, which are described and I pointed out in the following specification,and illustrated in the accompanying drawings, in which Figure 1 is a side View of the portions of a plow to which my invention mostly relates.

[ Fig. 2 is a view of the upper wedge. Fig. 3

is a view of the lower wedge. Fig. 4 is a bottom view of the plow-foot, showing one sweep only attached. Figs. 5 and 6 are front and back views, respectively, of one sweep. Figs.

7, 8, and 9 show a modification of the adjusting device in the sweep-stock and sweep. Fig. 10 is a top view of the plow, showing the marker. Fig. 11 is a front view of the plow, illustrating the marker.

5 The letter A designates the front standard,

B the back standard, 0 the cap-piece connecting the standards at the .top, and D the foot connecting them at the bottom.

The point E and mold-board F are secured as usual, and the handles H are made fast to the back standard. The beam J is supported on the cap-piece O. A side recess, 0, is formed at the cappiece by the upper flange, c, which continues down at the rear part, 70, and the lowerflange,c. Twobolt-slotsintheside wall ofthe said recess provide for the front bolt, d, and the back bolt, 6, and these bolts confine the beam J to the recess. The vertical breadth of the beam is such as to leave a space,

c", in side recess for the vertical adjustment of the beam. At the rear lower part of the recess is an inclined seat, 9, and an inclined slot, h, is in the side of the head. A wedge, f, 00-

' cnpics the inclined seat, and a bolt, h, passes through the wedge and occupies the said inclined slot and retains the wedge in position. This wedge f acts as an adjustable bearing for the rear extremity of the beam, and the man ner of shifting the wedge is apparent. A

5 wedge, L, is secured on top of the beam in such position that its pointend will take under the Serial No. 232,263. (No model.) '4

front upper flange, c, of the recess. This wedge has a shank, 2', provided with a slot, Z, and a bolt, m, passes through the said slot and beam. It will thus be seen the wedge is ad-. j ustable.

My improvement of the combined two wedges, one at the rear lowerpartof cap-piece and the other at the front upper part, both acting at the same time on the beam, provides fora range and a nicety of adjustment not possible with one wedge alone, as heretofore used.

One feature of my invention relates to the sweep-stock G. As heretofore constructed it 6 has been an objection that these parts become loose and require frequent tightening-up and adjusting. To obviate this I have contrived a plow-foot, D, and sweep-stock G, cast in one piece, (see Figs. 1 and 4,) with means whereby 7o the sweep I, attached to the stock, maybe adjusted to any desired position. The sweepstock comprises two wings. The end of each wing of the sweep stock (onewing being on one side ofthe foot and one on the other) is provided 5 with notches q (see Figs. 1 and i) and boltholes 1'. The sweeps I also have a bolt-hole,

r, and on the rear side (see Figs. 4 and 6) each sweep is provided with a lug, s, which has position on a central longitudinal line between the two cutting edges 1). \rVhen a bolt is passed through the hole 1" of the sweep and the hole 1" of the stock-wing, the lug s on the sweep will engage one of the notches 11 on the stock. As there are two holes on the stock and several notches, the outer end of the sweep may be adjusted vertically to the desired position. Bythisarrangementand construction for fastening the sweeps thesweeps are suited for either side of the plow-foot. They are ingo tel-changeable and reversible. When one outtingedge p on each becomes dull and worn, by placing the sweeps on the opposite sides of plow-foot and reversing them the other out tingedge will be brought into action.

Figs. 7, 8, and 9 show a modification of the means for effecting an adjustment of the sweep. Here the sweep has a rack, t, and the sweepstock G has one or two teeth, a, with which the said rack engages. Either of these 0011- I00 structions may be used with the sweep-stock G cast integral with the plow-foot D.

Another feature of my invention is the improved marker V, pivoted to the beam J. A oross-plate, w, is bolted to the top of the beam J, and projects beyond both sides. A rockshaft, :0, rests, in two bearings, 50, on the beam, and extends lengthwise thereof, and an arm, 1;, is rigidly attached at right angles to the said rock-shaft, and will project horizontally therefrom and rest on the cross-plate w. The marker-rod V is attached by its center at the end of the single arm 2;, and forms with said arm a T-piece. Each end of the marker-rod V has a seratch-point, g. It will thus be seen that the marker V o is pivoted on the draftbeam and may be tn mod to either side thereof, and the rod V will have a vertical position, one of the scratch points y being on the ground and the other pointing upward. A wire, 2', is attached by one end to the markerarm 2) and extends to the handles, or to the crossbar a between the handles. The plowman can thus easily reach the wire, and when at the end of the furrow, and turned around, he can, by pulling on the said wire 2*, turn the pivoted marker from one side to the other.

Instead of a wire, a rod, chain, or even a string will answer the purpose. The term wire in the claims, therefore, includes a rod, chain, or string.

Having described myinvention, I claim and desire to secure byLetters Patent of the United States- 1. In a plow, the combination of the standard having a eap-pieee, 0, provided with a beam-recess, a beam, J, in said recess, a wedge, L, resting on the beam, with its point end under the front upper flange, c,of said recess, and having a shank, 1', provided with a slot, and a bolt, m, passed through said shank-slot into the beam.

2. In a plow, the combination of the standard having a cap piece, 0, provided with a beam1'ecess,a beam, J, in said recess, and the combined two wedges,f L, both acting on the beam, one beingat the rear lower part and the other at the front upper part of said recess.

In testimony whereof I affix my signature in the presence of two witnesses.
